Drastically simplify the mapping from the declaration corresponding to
the injected-class-name of a class (or class template) to the
declaration that results from substituting the given template
arguments. Previously, we would actually perform a substitution into
the injected-class-name type and then retrieve the resulting
declaration. However, in certain, rare circumstances involving
deeply-nested member templates, we would get the wrong substitution
arguments.
This new approach just matches up the declaration with a declaration
that's part of the current context (or one of its parents), which will
either be an instantiation (during template instantiation) or the
declaration itself (during the definition of the template). This is
both more efficient (we're avoiding a substitution) and more correct
(we can't get the template arguments wrong in the member-template
case).

Invoke the Darwin assembler with -g instead of --gdwarf2.
The -g and --gdwarf2 options are currently synonyms to the Darwin assembler.
But clang itself does not recognize --gdwarf2, so if we want to experiment
with using clang, with its integrated assembler, to replace the default
assembler, it is necessary to use -g. <rdar://problem/10349486>

Fix part of PR11223 and probably a few dups as well. This teaches the
library search logic to "properly" handle multiarch installations. I've
tested this on both Debian unstable and the latest Ubuntu which both use
this setup, and this appears to work largely the same way as GCC does.
It isn't exactly the same, but it is close enough and more principled in
its behavior where it differs. This should resolve any failures to find
'crt1.o' etc on Debian-based Linux distributions. If folks find more
cases where we fail, please file bugs and CC me.
Test cases for all of the debian silliness are waiting both to simplify
the process of merging these down into the 3.0 release, and because
they're so crazy I haven't yet been able to really produce a fake tree
that represents what we need to test for. I'll eventually add them
though.
